Video Playback (yet another newbie question)

[Primefalcon]

I see that the mpeg player is capable of handling standard mpeg video


as of now I am converting widescreen video's using the following avconv command

Code: [Select]

avconv -i "inputFile.mp4" -r 20 -s 166x96 -b 128k "outputFile.mpeg"

I was wondering however if there is a better codec that mpeg1 supports such as mp4, webm, mkv's or whatever that allows same quality or so video's at smaller filesizes.

I download a lot of podcasts such as Linux action show.... Leo Laporte's this week in tech and so on..... considering there are quite a few.... a format that would allow smaller filesizes would be very handy
Post Merge: September 11, 2012, 05:03:41 AMOk I have been reading the wiki... and see that if I am right the optimal codec would be mpeg2.....

So I have the following bash script going through and doing my podcast folders

Code: [Select]

#!/bin/bash

convertEp()
{
	cd "$HOME/Music/gpodder-downloads/$1"

	for f1 in *.mp4; do
		f2="${f1%.mp4}.mpeg"
		
		if [ ! -f "Rockbox/$f2" ]; then 
			avconv -i "$f1" -s 176x100 -vcodec mpeg2video -b 229k -ab 192k -ac 2 -ar 44100 -acodec libmp3lame "Rockbox/${f1%.mp4}.mpeg"
		fi
	done
}

convertEp 'podcast 1 folder'
convertEp 'podcast 2 folder'
#and so on

Seems to be going pretty well, any comments welcome... also feel free to use the code

Formats with better compression such as mp4, webm and mkv need more processing power than what most Rockbox-supported players have.

Not sure if we have a language problem here -- MPEG1 is a codec, you can't put any other codecs in -- unlike formats like avi, which is a container format. Apart from that mpegplayer supports MPEG1 and MPEG2, both with mp3 audio. That's all you can use.

I meant mpegplayer not the mpeg codec sorry... up too long plays havoc on typing....

I kinda figured as much about other codecs... was just hoping though.... I've go back to using mpeg1 over mpeg 2 since that does seem to be better at lower resolutions and bit rates unless I am missing something
